Abstract: ABSTRACT OF THE DISCLOSURE       A microprogrammable peripheral controller in addition to being operative to controlling plurality of input/output devices in response to commands for processing information signals from a magnetic medium also includes apparatus for independently establishing a minimum operating capability within the controller.  The apparatus  includes a read-only control store arranged to store micro-instructions and a limited number of basic bit patterns.          The apparatus in response to an external control signal is operative to condition the data recovery apparatus included in the controller to receive the blocks of synchronization and data patterns arranged in a predetermined format and generated from basic bit patterns obtained from the control store.  Simultaneously therewith, the apparatus inhibits normal transfer of information from the magnetic medium.  Additionally, a plurality of record error indicator circuits included in the data recovery apparatus are operative to be switched during the processing of each of the blocks of bit patterns transferred through the recovery apparatus.  The apparatus further includes comparison circuits which compare the state of the record error indicators with a predicted bit pattern for detecting whether the recovery apparatus is operating properly in processing the block of bit patterns transferred thereto.  The states of other indicator storage circuits are modified to signals indicative of conditions occurring during the transfer of the generated bit patterns.          The comparison circuits also compare the states of these circuits with a predicted bit pattern as further verification of recovery apparatus operation.

Abstract: An autonomic solar heat collecting system is provided. The solar collecting panel includes a flat outer surface adapted to be exposed to the direction of the radiation of the sun and a flat or formed inner sheet connected to, and closely spaced from the flat outer surface section to provide a thin plate-like passageway between the inner sheet and the outer sheet.  Means are provided for allowing entrance of a fluid into the bottom cavity and gravity return means are provided for removal of the fluid from the other, or top, cavity.  A heat transfer medium flowing within the plate-like passageway as a thin fluid membrane absorbs the energy of the sun's radiation.  A through-put heat transfer reservoir is provided for accepting the heat transfer medium for the solar panel.  Heat sensing means are provided for monitoring the temperature within the reservoir.  Low pressure means are provided for returning the heat transfer medium to the solar panel from the reservoir.  Low pressure means are provided for regulating the flow of the medium from the reservoir to the solar panel.  Finally means are provided to supply such low voltage, low power for the operation of the system.  Thus, an essential feature of the autonomic system is low wattage, low power pump means activated by a small predetermined temperature differential, and the means for providing power for the operation of the system is solar cells or wet or dry batteries. The solar panels can therefore be used in a conventional manner, for heating or for air conditioning.

Abstract: METHODS AND SYSTEMS FOR USE WITH PULSE TRAIN CIRCUITRY    Abstract of the Disclosure Disclosed are apparatus and methods for determining the actual, standardized volume of fluid flowing in a flow-line.  A flow meter in the line measures volume and provides the measured value in the form of a pulse train.  Compensating means change the number of pulses in the pulse train as required to compensate for the difference between the actual fluid temperature and a standard reference temperature.  The pulse train is also compensated to correct for meter error.          Digital verification means are provided for verifying that the compensating means are working properly.  In the methods, an input counter connected to the input of a circuit in the system is gated to start counting pulses applied into the circuit while an output counter is simultaneously gated to start counting the pulses out of the circuit.  At the end of the test period, the input and output counts and other known input values are employed as the variables in a mathematical equation representing the circuit function.          Balancing of the equation using these variables verifies that the circuit is operating correctly.  The method and apparatus may be employed to verify proper operation of other digital computing circuits or to establish a comparative relationship between a plurality of electrical pulse train producing means.

The apparatus may com-prise one device having means displaying a plurality of symbols, where-in each symbol represents one of the binary connectives, the means hav-ing the plurality of symbols in a predetermined configuration.  The apparatus may comprise are than one device, in which case the devices are movable and belong to a set, and when used in a selected combina-tion, the combination of movable devices is capable of being assembled in a predetermined comformation.     Whether the apparatus comprises one or more devices, each of the symbols has a shape selected to indi-cate a selected number of from zero to four components arranged with respect to the quadrants of a set of Cartesian coordinates, wherein the shape has iconicity, frame consistency, and eusymmetry with re-spect to the quadrants of Cartesian coordinates, and wherein the alignment of the shape is symmetry positional with respect to the x-y axes of the Cartesian coordinates.  Further the shape is taken from at least six letter-shapes capable of generating 16 symbols that can be readily assigned a phonetic value, the symbols having four levels of symmetry such that two of the symbols are two-way self-flippable and self-rotatable, two of the symbols are not self-flippable but are self-rotatable, four of the symbols are one-way self-flippable but are not self-rotatable, and eight of the symbols are neither self-flippable nor self-rotatable.     The symbols, the configuration of the symbols, the set of movable devices, and the conformation of the devices are selec-ted so that the one device is, or the devices are, adaptable by trans-formations taken from the group consisting of reflections, rotations, translations, counterchanges, and combinations thereof to display and perform the operations.
